To all 'whom t my concern:

Be it known that l, GEORGE DAMANIS, a citizen of the United States,residing at New York, in the county of New York and State of New York,have invented certain new and useful Improvements in Locks; and lf dodeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which it apertains to make and use the same.

ltly invention relates to improvements 1n house and apartment door locksand more particularly to those of the type having a locking bolt whichis tripped by lnward movement of the= usual beveled latch, incident toclosing the door, whereby said locking bolt is projected to co-act wilththe latch in doubly locking the door.

One object of my invention is to provlde alock of the character setforth provided with means for locking the bolt against projection everytime the door is closed, for instance during the day time, this means,however, being movable to an inoperative position so that whenever it isdesired to have the bolt project automatically with closing of the door,this can be done.

A further object is to provide improved means for tripping the boltholding tumbler when the door is closed, permitting a spring to comeinto play to project the bolt.

Yet anotherobject is to provide a novel arrangement of parts wherebyboth the locking bolt and the latch may be simultaneously retracted bymeans of a key, the bolt being held in retracted position while thelatch is released to be again projected under the influence of itsspring.

With the foregoing in view, the invention resides in the novel subjectmatter hereinafter described and claimed, the description beingsupplemented by the accompanying drawings.

Figure 1 is an elevation, partly in section, showing a lock constructedin accordance with my invention, the bolt and the latch being shown inlocked position..

Figure 2 is a view similar to Fig. 1, showing the locking bolt and thelatch partially withdrawn.

Figures 3 and t are detail perspective views showing the additions whichl have made to a well hewn lock structure, to carry out my invention. vy

lfn the drawings above briefly described, the numeral ldesignates asuitable lock casing containing a spring pressed beveled latch 2 and alocking bolt 3 provided with a projecting spring d. A spring-appliedtumbler 5 is pivoted at 6 to the locking bolt 3 and is cooperable with apost 7 in the casing to hold the bolt in either projected or retractedposition. The numeral 3 merely designates a well known rocker controlledby a finger piece from the inside -of the door,

for releasing thetumbler 5 and retractingl the. locking bolt 3 whendesired, without the necessity of using a key. When it is desired tohold this bolt in retracted position, regardless of release of itstumbler 5 by means yet to be described, this may be done by means of apin 9 passing slidably through a slot 10 in the casing and capable ofbeing moved into engagement with a shoulder 11 on the bolt 3, when thelatter is fully retracted.

For retractin the lock 3 by hand, and releasing its tum ler 5, anordinary cylinder type of locking mechanism is provlded within anopening 12 in the casing, this mechanism. however being omitted for sakeo clearness.

'lhe numeral 13 designates a lever which may well be ulcrumed upon thepost 7, the lower end of said lever having a pin and slot or othersuitable slidin" connection 14 with the latch 2, while t e upper end ofsaid lever is provided with a shoulder 15 engaged by a nose 15 on a cam16 located behind the bolt 3 and pivotally mounted on a suitable stud orthe like 17. A cam actuator 18, preferably in the form of a horizontallever, is fulcrumed at 19 to the bolt 3 and as here shown, is providedwith a lateral lug 20 cooperable with the curved edge 21 of the cam 16,for thev purpose of rocking said cam about its pivot 17, as the actuator18 is forced inwardly by inward movement of the bolt 3, under theiniuence of the key operated mechanism. The end of the actuator 18,remote from its pivot 19, is connected by means of a link 22 or othersuitable means, to the tumbler 5. Since the actuator is tied to thetumbler 5, it cannot have vertical movement independent of the tumblerand therefore the actuator will be held against upward swinging when thebolt 3 moves inwardly andconse uently causes the lug 20 to tilt the cam16 ownwardly and furthermore, when the bolt is fully retracted and thetumbler 5 ava-in rises to an operative position to holdD said boltretracted, the tumbler pushes upwardly upon the link 22 and thus swingsthe actuator 18 upwardly, thereb releasing the pressure of the lug 20upon the cam 16 and permitting the latch 2 to again project under theinfluence of its spring. rlhis spring, a portion of which is designatedby the reference character 23, may well act upon the lever 13.

While any desired connections may be employed between the link 22 andthe parts 5 and 18, l prefer to establish these connections by means ofloosely intertting notches in the several parts as shown moreparticularly at 24 in Fig. 3.

From the construction so far described, it will be seen that when thebolt 3 is moved inwardly by key operated mechanism (not shown) the lug20 and the actuator 18 tilt the cam 16, therebyrocking lever 13 andretracting the latch 2, so that the door.

can be opened. As soon as the key operated mechanism however permits thetumbler 5 to come into play to hold the bolt 3 retracted, the link 22moves the actuator 18 upwardly, releasing the vpressure of lug 20 on cam16 and permitting the latch 2' to again project, while the bolt 3remains retracted. Now, it it is desired that the bolt 3 shall not beprojected the next time the door is closed, the pin 9 is moved intoengagement with the shoulder 11. Utherwise, closing of the door andinward movement of the latch 2, incident to this closing, will causeprojection of the bolt 3 under the infiuence of its spring 4c, due tothe tact that ll provide a pin or other projection 25 on the lever 13for contacting with and releasing the tumbler 5 when the latch 2 ismoved inwardly.

Assuming that the bolt 3 is held in retracted position by the tumbler 5,that the pin 9 is not engaged with the shoulder 11, and that the door isin open position, it will be seen that closing of this door will causethe latch 2 to move into-the casing, thus rocking the lever 13 andcausing pin 25 to release the tumbler` 5, whereupon the spring t comesinto play to automatically project the bolt 3 for cooperation with thelatch 2 in doubly locking the door.

As excellent results may be obtained from the details disclosed, theyare preferably followed, but it is to be understood that Within thescope of the invention as claimed, numerous minor changes may be made.For instance, although ll have used well Lavaeaa known lock parts andhave merely added' the link 22 and the pins 9 and 25, it will beunderstood that if desired, the invention can be carried out in otherways. It may me further stated that all parts shown below the broken.line'A, are well known, for the purpose of controlling the latch 2 byhand from the usual knob shaft.

I claim:

1. A lock comprising a casin containing a spring-pressed latch, a loc-controlled bolt and a lock-controlled tumbler for said bolt; a movablemember mounted in said casing and operatively associated with said latchfor withdrawing the same, an actuator for said movable member mountedmovably on said bolt and operative to effect withdrawal of said latchautomatically when the bolt is withdrawn, and a connection between saidactuator and said tumbler for automatically movin said actuator out ofoperative relation wit said movable member when said tumbler returns tooperative position with the bolt retracted.

2. A lock comprising a casing containing a spring-pressed latch, alock-controlled lbolt and a lock-controlled tumbler for said bolt; amovable member mounted in said casing and operatively associated withsaid latch for withdrawing the same, an actuator for said movable membermounted movably on said bolt and operative to eect withdrawal ofsaidlatch automatically when the bolt is withdrawn, and a linkconnecting said actuator with said tumbler for automatically moving saidactuator out of operative relation with said movable member when saidtumbler returns to operative position with the bolt retracted. i

3. A structure as specified in claim 2; the connections of said linkwith said tumbler and actuator being eifected by providing said link,tumbler and actuator with loosely interitting notches.

4. A door lock comprising a casing containing a spring pressed beveledlatch, a spring-projected locking bolt and a tumbler for normallyholding said bolt retracted; means in the casing, for automaticallyretracting the latch when the bolt is retracted, including a movablemember adjacent said tumbler, and a projection on said member operativeto release said tumbler and thereby eect projection of the boltautomatically when the latch is forced inwardly by closing the door.

5. A door lock comprising a casing containing a spring pressed latch, abeveled, spring-pressed lock-controlled bolt and a lock-controlledtumbler for said bolt; a lever fulcrumed in the casing and extendingtransversely of the bolt, said lever being con.- nected with said latch,a movable member mounted in the casing and acting on said lever forretracting the latch, an actuator for said movable member mountedmovably the latch, and a projection on said lever on the boltand activeto eect retraction of adapted to strike and release said tumbler thelatch when the bolt is retracted, means when 'the latch is forced intothe casing by 10 for automatically disengagmg said actuator closing ofthe door.
